Bali is one of Indonesia’s most popular destinations, attracting millions of international visitors every year. From its beaches and mountains to cultural attractions and vibrant cafés, the island offers something for every traveller. However, like many tropical destinations, Bali is also home to mosquito-borne diseases, including dengue fever.
Understanding dengue in Bali is essential for anyone planning a holiday, business trip, or long-term stay. Although most people recover fully with appropriate care, dengue can become serious if warning signs are ignored or treatment is delayed.
Why Dengue in Bali Should Not Be Ignored
Indonesia continues to report dengue cases every year because its warm temperatures and seasonal rainfall create ideal breeding conditions for mosquitoes. In Bali, especially during wet months, the mosquito population rises sharply.
According to data from Indonesia’s Ministry of Health covering 2018–2025, children remain among the most vulnerable groups to severe dengue infection. The 5–14 age group consistently records the highest proportion of dengue-related deaths compared with other age groups.
By 2025, 59% of dengue-related deaths occurred among children aged 0–14, while children aged 5–14 accounted for 41% of those fatalities. At the same time, adults aged 15–44 represented the largest proportion of reported dengue cases, accounting for approximately 42% of infections.
These figures show that dengue is not only a concern for children. Adults, including international visitors and expatriates, are also at risk, particularly when spending extended periods outdoors.

The “Plus” element of the strategy focuses on personal protection measures, which are essential for tourists in Bali.

The dengue virus increases the permeability of blood vessels, causing blood plasma to leak into surrounding body tissues. This process lowers effective blood volume and can lead to a sudden drop in blood pressure, even if the patient shows no external signs of dehydration.
Treatment for dengue fever:
- Maximum Fluid Intake: Patients must drink plenty of fluids. Oral rehydration solutions, clear broths, and fresh coconut water are ideal choices. Fresh coconut water provides natural electrolytes that help restore fluid balance effectively.
- Monitoring Platelet Counts: Medical professionals track a patient’s platelet level closely through simple blood tests. A sharp fall in platelets indicates severe dengue, requiring immediate clinical observation.
- Medical Insurance Protection: Because recovery can take a week or longer, having comprehensive travel insurance that covers emergency hospital stays is essential. Private healthcare costs in tourist centers can accumulate quickly without proper coverage.
Finally, long-term visitors or frequent travelers should speak with a medical professional regarding the dengue vaccine prior to travel. Vaccination can offer an additional layer of protection against severe illness for those spending extended periods in endemic regions.
